Polyesterijira rekugadzira rinowanzo torwa kubva mupetroleum.Iri jira nderimwe remachira ane mukurumbira pasi rose, uye rinoshandiswa muzviuru zvemhando dzakasiyana dzevatengi nemaindasitiri.
Kemikari, polyester ipolymer inonyanya kuumbwa nemakomponi mukati meiyo ester inoshanda boka.Mazhinji ekugadzira uye mamwe zvirimwa-based polyester fibers anogadzirwa kubva ethylene, inova inoumba petroleum inogona zvakare kutorwa kubva kune mamwe masosi.Nepo mamwe marudzi epolyester ari biodegradable, mazhinji acho haasi, uye kugadzirwa kwepolyester uye kushandiswa kunobatsira mukusvibisa pasirese.
Mune mamwe maapplication, polyester inogona kunge iri iyo chete inoumba zvigadzirwa, asi zvinowanzoitika kuti polyester isanganiswe nekotoni kana imwe fiber chaiyo.Kushandisa polyester muzvipfeko kunoderedza mitengo yekugadzira, asi zvakare inoderedza kugadzikana kwembatya.
Kana yakasanganiswa nedonje, polyester inovandudza kuderera, kusimba, uye kuunyana chimiro cheiyi inogadzirwa zvakanyanya-yakasikwa fiber.Polyester jira rinopokana zvakanyanya nemamiriro ezvakatipoteredza, izvo zvinoita kuti ive yakakodzera kushandiswa kwenguva refu mukushandiswa kwekunze.
Iro jira ratinoziva sepolyester rakatanga kukwira rakananga kune iro rakakosha basa muhupfumi hwazvino muna 1926 seTerylene, iyo yakatanga kugadzirwa naWH Carothers muUK.Mumakore ose ekuma1930 nema1940, masayendisiti eBritain akaramba achigadzira nzira dziri nani dzemucheka we ethylene, uye kuedza uku kwakazopedzisira kwawana kufarira kwevashambadziri veAmerica nevatsva.
Polyester fiber yakatanga kugadzirwa kuti ishandiswe nevanhu vakawanda neDuPont Corporation, iyo yakagadzirawo mamwe akakurumbira mafibhi ekugadzira senaironi.Munguva yeHondo Yenyika II, masimba eAllied akazviwana ari kuwedzera kudiwa kwefibers nezvimwe zvehondo, uye mushure mehondo, DuPont nemamwe makambani eAmerica vakawana musika mutsva wevatengi wezvigadzirwa zvavo zvekugadzira mumamiriro ezvinhu ehupfumi hwepashure pehondo.
Pakutanga, vatengi vaifarira iyo yakagadziridzwa chimiro chepolyester zvichienzaniswa neakasikwa fiber, uye mabhenefiti aya achiri kushanda nanhasi.Mumakumi emakore achangopfuura, zvakadaro, kukuvadza kwezvakatipoteredza kweiyi faibha yakagadzirwa kwave kujekeswa zvakadzama, uye chimiro chevatengi papolyester chachinja zvakanyanya.
Zvakadaro, polyester inoramba iri imwe yemachira anogadzirwa zvakanyanya munyika, uye zvakaoma kuwana zvipfeko zvevatengi izvo zvisina kana chikamu chimwe muzana chepolyester fiber.Zvipfeko zvine polyester, zvisinei, zvinonyunguduka mukupisa kwakanyanya, nepo mafibhi mazhinji echisikigo anopisa.Faibha dzakanyungudutswa dzinogona kukonzera kukuvadzwa kwemuviri kusingagadzirike.
